High working loads and easy installation. The new generation of concrete screws in A4 stainless steel. For flush mounting of e.g. staircase railings or handrails in concrete
  • The new thread geometry ensures smooth screwing into the concrete and thus greater efficiency

  • The fastest type of fastening for medium and heavy loads

  • Three effective anchorage depths allow flexible application

  • Attachments can be adjusted up to twice retrospectively, for example to be able to align staircase railings or anchor plates (observe installation instructions)

  • Minimum spacing and edge distances due to very low expansion effect

  • Attractive, flush-mount installation possible
Proof of Performance

European technical assessment ETA-22/0123 for fixing point option 1, cracked and non-cracked concrete:


  • Static and quasi-static effects (∅6 - ∅10)

  • Seismic effect, performance category C1 (∅6 - ∅10)

  • Fire resistance R30, R60, R90, R120
Notice

From size 8, we recommend the use of a suitable tangential impact screwdriver for installation. The recommended nominal torque must be observed. When used outdoors, the drill hole can be sealed with WIT-BS injectable mortar.

Application area

Fixing point with approval (∅6 - ∅10):


In normal weight concrete C20/25 to C50/60 (cracked and non-cracked concrete)



Specifically designed for attractive flush-mounting



Suitable for mounting medium to heavy loads in concrete:


  • Attachment of e.g. staircase railings and balcony balustrades, handrails, steel constructions, wooden substructures, metal profiles etc. in in-place installation

  • Mounting under seismic conditions in earthquake areas

  • Mounting in areas under exposure to fire


W-BS 2/A4 (A4 stainless steel) can be used in dry indoor conditions, outdoors (including in industrial atmospheres and close to the sea) or in wet rooms, provided that no particularly aggressive conditions are present



For use in concrete < C20/25 and pressure-resistant natural stone (without approval)
